Now that Marian has broken their engagement, Lindsay Trevor finds danger welcome, even though it means dyeing his hair red and impersonating his cousin Froth as Restow’s secretary.
Who is this Restow, huge, good-natured – is he fabulously rich or desperately poor? Is he the mysterious Vulture, that master of deceit and manipulation? And there is Restow’s wife, the big, tempestuous snake-charmer Gloria; Dalton, the lean, black, spider-like librarian, and Elsie Manning, Froth’s friend, who is afraid – of what? When Marian comes back into his life most unexpectedly, Lindsay enters a desperate struggle against the Vulture, with Marian’s life at stake.
